Description
When we set out to design the HERON, we didn't want to create just any road bike helmet. We wanted to create the ultimate road bike helmet! If you think aerodynamics come at the cost of an overheated head and painful neck – think again! After extensive wind tunnel testing, we came up with a design that directs cooling air over the entire head via deep ventilation channels yet doesn't look or feel too bulky in the process. At only 258g, our aero helmet gives you an extra portion of speed even on long-distance rides, while providing maximum comfort.
Calculate your size!
Fill in your height and inseam below and click 'Calculate my frame size' to see what size you need. Measure your inseam as follows:
- Stand barefoot with your heels against the wall. Place your feet about 15 centimeters apart.
- Grab a book and place it between your legs, with the short side of the book against the wall. Press the book upward against your crotch, mimicking the idea of a bicycle seat.
- Measure the length from the top of the book to the ground, the distance you measure is your inseam.
